[Industrial Application Field] The present invention provides a side frame that is used for a frame scaffold temporarily installed along the outer wall surface of a building, etc., and has the function of a strength member in place of braces, a handrail, and a protection function against falling objects. Regarding. [Prior Art] As this type of framework scaffold, the one shown in FIG. 7 is currently in general use. That is, in the figure, a plurality of torii-shaped building frames 90 are arranged side by side at predetermined intervals, and the required number are connected in the vertical direction, and intersecting braces 91 are installed between adjacent building frames. It will be done. And the horizontal land 90a, 90 of the adjacent building frame
Scaffolding board 2 is spanned between a and work floors A 1 and A 2
... will be ensured. Supports 92 are installed on the top building frame 90.
is erected and the handrail 93 is set. [Problems to be Solved by the Invention] However, the above-mentioned known framework scaffolds have the following problems. During assembly or disassembly (reassembly) work, there is no handrail for ensuring safety for workers standing on the scaffolding boards 2 of each stage, and they are forced to perform extremely dangerous work. Frame scaffolding usually has a curing frame (framed metal mesh) or curing net (mesh sheet) stretched on its outer surface for the purpose of curing fallen objects. Such curing is carried out after all stages of scaffolding have been erected, but in reality there is a risk of accidents caused by falling objects even during erecting, and it cannot be said to be a sufficient measure. Furthermore, both the curing frame and the net are troublesome to install and require considerable effort. Nets are generally 5100mm long and are designed to cover three levels of the building frame with one piece, but attaching to the building frame is a hassle as it requires tying it to the building site with a string. It is. The curing frame has a structure in which curing clamps are attached to two places, the building frame and the building site, and the holes in the curing frame are fitted into the joints provided on these clamps, which requires time-consuming work to install. becomes. Furthermore, if the net is not securely fixed to the building site, it will flap around in the wind and become a source of noise. Furthermore, even if only one part is damaged, the entire large piece needs to be replaced, which is not only disadvantageous in terms of cost, but the large size of each piece also makes it difficult to handle when installing, removing, storing, cleaning, etc. I have to. The side frame of the present invention is a scaffolding component for solving these problems of conventional scaffolding. [Means for Solving the Problems] As shown in FIGS. 1 and 2, the present invention provides a side frame main body 30 based on a rectangular rigid frame, and a side frame main body 30 that is also rectangular and almost the same as the side frame main body 30. The side frame main body 30 has a width W 2 that approximately corresponds to the spacing l of the building frames 1 arranged in parallel, and the side frame body 30 has a width W 2 that approximately corresponds to the arrangement interval l of the building frames 1 arranged in parallel. The side frame main body 30 is further provided with an engagement means 32 for engaging the net 31, and the net 31 can be attached and detached by this engagement means. The gist of this invention is a side frame for a framed scaffold, which is characterized in that it is attached to a frame. [Function] As shown in FIG. 4, the side frame 3 of the present invention has the following features:
It is installed entirely between adjacent building lots 10 on the outer side of building frames 1 arranged in parallel. In this attached state, the side frame 3 provides the scaffold with strength against horizontal forces by its own frame rigidity, that is, takes on the function of replacing braces. In this case, the net 31 closes the entire surface of the opening on the outer side of the scaffold and functions as a protection against falling objects. The side frame 3 equipped with this net is set in parallel with the assembling of the building frame 1 at each level of stacking when the scaffolding is assembled, and this makes it possible to protect fallen objects even when the scaffolding is being erected. becomes. Moreover, the implementation of falling object protection measures is completed at the same time the scaffolding is erected, so there is no need to carry out protection measures as a separate task after the scaffolding is erected, unlike with conventional curing nets. The effort required,
Saves time. Not only that, but the frame 30 itself becomes a handrail,
The safety of workers will also be ensured during the process of assembling the scaffolding. Furthermore, since each net 31 is small in size, it does not flap or make noise unlike a curing net, and is configured to be detachable from the side frame body 30, making it easy to clean. All you have to do is remove it from the main body 30. Furthermore, during transportation, storage, etc., it can be handled while attached to the side frame body, and is not bulky and easy to handle. [Embodiment] Figures 1 and 2 above show an embodiment of the present invention, in which A is a perspective view illustrating the overall structure, and B and C are partially enlarged views. According to FIG. 1, the side frame 3 has a rectangular shape as a whole and is made up of a side frame body 30 and a net 31. The side frame main body 30 that goes around the circumference includes a reinforcing member 301 disposed inside thereof, and joining pieces 302 provided near the four corners of the outer frame body 300. The side frame main body 30 is constituted by a round pipe, and on its inner surface, engaging means 32 for attaching the net 31 are provided. The engaging means 32 shown enlarged in FIG. , the hook part is fitted around the side frame body 3.
It is constructed so that it does not protrude outward from the outer circumferential surface of 0. Each of the engaging means 32 is formed inside the frame itself so as to be bent toward the outer periphery. The dimensions of the side frame body 30 are such that the outer width W 2 is approximately equal to the inner dimension W 1 between the adjacent building lots (hereinafter simply referred to as adjacent building lots) 10, 10 of the building frames 1 that are arranged in parallel as described below. We are doing so. Height H 2 is the height H 1 of building lot 10
It is approximately half the size of the original. The reinforcing material 301 forms a water-like shape within the side frame body 30 and provides high rigidity to the side frame body 30. Needless to say, the method of taking the reinforcing material 301 is not limited to this, and various modifications are possible. Some of the variations are shown in Figure 3. The connecting pieces 302 are provided near the upper and lower ends of both vertical members of the side frame main body 30. The side frame main body 30 is attached to fit between the adjacent buildings 10, 10 by the connecting pieces 302. The net 31 is a peripheral portion 311 that is finished with a cross.
The hole 311b drilled in the hole 311a is hooked onto the engaging means 32 to be fixed to the side frame main body 30 and can be removed. Another way to attach the net 31 is to pass a string through the hole 311b and attach it to the side frame body 30.
A method of fastening the net 31 to a rectangular frame, and a method of attaching this frame to the side frame main body 30 are possible. In the side frame 3 shown in FIG. 2, the side frame main body 30 is made of angle material, and on the inner surface of the vertical flange of the angle material,
Engaging means 32 for attaching the net 31 are provided. As with the side frame 3 in Fig. 1, the engaging means 32... may include one in which a hook is separately attached to the side frame body 30 (FIG. (C) in the same figure is possible. According to this side frame 3, the net 31 is housed in a space surrounded by the vertical flange portion of the angle member constituting the side frame body 30 and the flat flange portion bent from the vertical flange portion toward the inside of the frame. The net 31 may be attached directly to the engaging means 32, or the net 31 may be temporarily fixed to a rectangular frame, and this frame may be attached to the side frame body 30. The other configurations are the same as the side frame 3 of FIG. 1, so detailed explanation will be omitted. Next, a framework scaffolding according to an example of a usage mode of the side frame configured as described above will be explained with reference to FIG. 4. This scaffold as a whole has a multi-tiered work floor A 1 ,
It consists of a working floor unit U 1 forming A 2 . The basic components of the work floor unit U1 are a building frame 1, a scaffold board 2, the side frame 3 on the outside side, and a side frame on the inside side (frame side). Since the side frame 3 has already been explained, the configuration of each other than the side frame 3 will be explained. ○ Building frame 1 Figure 5 shows the front view. According to the figure, the building frame 1 is an H-shaped frame, and includes a pair of building lots 10, 10, a horizontal lot 11 that connects the two building lots at the upper and lower division points, and a horizontal lot 11 on the lower side of the horizontal lot 11, Inverted U-shaped reinforcing material 12 placed between the bases 10 and 10
The basic parts are made up of. All structural members are round steel tubes. A connecting pin 13 for connecting the building frames to each other is attached to the upper ends of both building sites 10, 10. Furthermore, on each of the building lots 10, 10, engagement pins 15 with spring-type retaining pieces 150 are provided at a total of four locations near the upper and lower ends, directly above and directly below the mounting position of the horizontal lot 11. . The arm lock and the engagement pin 15 for locking the side frame are all shaped to protrude into the interior of the frame itself. A through hole 100 extending in the longitudinal direction of the horizontal lot is provided in a portion of each building site 10 directly below the attachment position of the horizontal lot 11. This through hole 100 is used to connect between buildings, to install scaffolding equipment such as morning glory, etc. The reinforcing material 12 spanning both building lots 10, 10 is
It is connected to the horizontal floor 11 by a connecting plate 120 at its center. Connection plate 1
A through hole 120a is drilled in the through hole 120, which can be used to attach a tie rod or the like for supporting reinforcement when attaching a morning glory or the like using the through hole 100. Furthermore, if the temporary construction is intended for buildings in general, a frame width of less than 900 mm, which is the ``simple frame'' width, is sufficient. Regarding the height H, from the perspective of securing the necessary space for work based on the height of the person, the
Approximately 2000mm is appropriate. Scaffolding board 2 The scaffolding board 2 is normally used, and is provided with engagement claws 20, 20 at both ends for engagement with the building frame horizontal area 11. ○ Side frame on the inner surface side (body side) This is generally used as a handrail and strength member, and is a handrail frame 35 as shown in Figure 6A, or a handrail material 36 as shown in Figure 6B. A combination of the diagonal member 37 and the diagonal member 37 is used. Next, the arrangement and combination of the constituent elements will be explained. First, the required number of building frames 1 are arranged in parallel at a predetermined interval l, and the required number of stages are added in the vertical direction as well. A jack base 8 is attached to the bottom end of the lowest building frame. The placement interval l is 1829mm, 1524mm for inch size,
It will be set at around 1219mm and 914mm. The connection in the vertical direction is performed by the above-mentioned connection pin 13 at the upper end of the building site 10, and the locking is performed by an arm lock or the like. Scaffolding boards 2 are connected and spanned between adjacent horizontal lots 11, 11 of each tier of such a building frame 1, forming working floors A1 , A2 ... for the number of erected tiers of the building frame. ing. The engagement with the horizontal ground 11 is done using the engagement pieces 2 on both ends of the scaffolding board 2.
According to 0.20. The side frame 3 is provided between each adjacent building site 10 on the outer surface side (reverse frame side) in each stage of the building frames 1 . The height H2 of the side frame 3 is half the height H1 of one building frame, and one side frame 3 is built above and below the work floor A level at each stage. . Although some parts are omitted in FIG. 1 for convenience of illustration, the side frame 3 is provided so as to cover the entire outer surface. The side frame 3 is fixed using the four connecting pieces 302 of the side frame...
is fitted into the engagement pins 15 with retaining pieces of the building lots 10, 10. In the above-mentioned attached state, each of the side frames 3 fits between the buildings 10, 10 on both sides, and has almost no gap between them. Although the side frames on the inside side (frame side) are not shown in Figure 1, their height is half the height H1 of one building frame, and one unit is placed for each level of building frame 1. It will be built above the A level of the work floor. In the illustrated example, a diagonal member 5 is attached to the lower side of the lowermost work floor A1 instead of the side frame. In the scaffold constructed as described above, the side frames 3 in the assembled state function to horizontally solidify each stage of the work floor unit U1 , and as a result, the whole becomes solid. Further, the side frame 3 is attached between each of the adjacent buildings 10, 10, and the net 31 as a whole completely covers the outer surface of the scaffold, thereby achieving protection against fallen objects. Next, the scaffolding is removed as follows. First, the lowest building frame 1 of work floor unit U 1 ...
are installed, diagonal members 5 are set on the lower side between each building frame, and scaffolding boards 2 are stretched between adjacent horizontal lots 11, 11. After doing this, the unit
Go up onto the scaffolding board 2 of U1 and attach the outer side frame 3 and the inner side frame on the lowermost upper side. Once the bottom tier is completed in this way, the building frame 1 of the second tier is added on top of it, the lower side frame 3 of the second tier is attached, and the scaffold board 2 is hung. In this manner, the work floor unit U1 is assembled step by step in parallel from the bottom. When dismantling, follow the exact opposite procedure and work your way down from the top. In such assembly and disassembly work, the worker stands on the scaffolding board 2 for each tier and attaches the upper outer side frame 3 and the inner side frame 3 to the tiered building frame 1 and then directly. The process proceeds by adding the upper building frame 1 → installing the lower outer side frame 3 and the scaffolding board 2 to the building frame 1 in this order, but in this case, the subsequent work is always performed on the step being worked on. The work will be carried out with side frames that act as handrails on both the outside and inside sides, allowing for safer work. Although the case where the H-shaped building frame 1 is used has been described above, the application of the side frame of the present invention is not limited to this, but can also be applied to scaffolds using a general torii-shaped building frame. [Effects of the Invention] The side frame of the present invention described above has the following features and advantages. ○ When incorporated into a scaffold, the rigidity of the frame resists horizontal forces, giving the scaffold as a whole a high level of strength. ○ In addition, the net 31 provided thereon covers the entire outer surface of the scaffold without any gaps, thereby ensuring the protection of fallen objects. ○ When the scaffold is being erected, each stage is set in parallel with the erecting, so it functions effectively as a measure against falling objects during the scaffold erecting process. In addition, it is reasonable to complete measures to prevent falling objects from occurring as soon as the scaffolding is erected, and the time and effort required for temporary scaffolding can be greatly reduced. ○ It is also effective as a handrail, and when used in conjunction with an H-shaped building frame, it guarantees the safety of workers even when assembling scaffolding. ○ Furthermore, since the size of each net is small, it does not flap around or make noise unlike conventional curing nets. In addition, it is configured to be detachable from the side frame body, making it easier to clean by removing it from the body, and for transportation and storage, it can be handled while attached to the body without being bulky. It becomes easy.
